Study on Multi-trait Comprehensive Evaluation of E.tereticornis and E.urophylla Provenances

The varied and genetic analyzed results of growth traits and survival rate of 8 Eucalyptus urophylla and Eucalyptus tereticornis provenances showed that there were highly significant differences in all traits except H/DBH at provenance level.Heritability of provenance and individual was 43.25%～88.14% and 16.00%～65.01% respectively.H,DBH and SV were closely significant Positive correlation and none closely correlation with the survival rate and H/DBH.At 3.5 years age,14532 of E.urophylla and 13541 of E.tereticornis was the fastest growing provenance which it's SV reached 0.09636m3 and 0.04516m3 respectively.General,13541,13544 of E.tereticornis and 14532,14531 of E.urophylla was selected the better provenances by comprehensive evaluation,the breeding valur of all provenance were Estimated synchronously.
